12 - Dynamic Message Signs

Description

This project has two components: 1) KDOT installing "end of queue warning" Dynamic Message Signs along the 2–lane portion of K–10 and 2) other potential Dynamic Message Signs at strategic locations in the Region to aid in providing traffic information to the public and managing congestion and event traffic.
KDOT is constructing a system for "end of queue warning" along the 2–lane portion of K–10. These boards will work in conjunction with 6 radar sensors measuring vehicle speeds along various spots along K–10. When there are slowdowns or vehicle queues at the Wakarusa traffic signal or elsewhere along this 2–lane corridor, real–time messaging will be displayed on the nearest upstream board alerting drivers of the congested conditions ahead. There will be 2 DMS boards and 3 traffic sensors for each travel direction of K–10. In the event of a complete closure along this highway corridor, the most upstream boards will advise drivers to divert onto City of Lawrence surface streets, namely Iowa and Clinton Parkway. This system will be operational starting in the Summer of 2021.

The other potential DMS signs will provide event, detour, parking, and other information to travelers as they enter the City of Lawrence. Locations will be selected prior to critical travel decision points to encourage travelers to take alternate routes when there is congestion on main roads. A camera would also be installed at each DMS location. The cameras will be used to monitor the status of the DMS.
